The time is now for me to sell one of these fine amps to support my speaker project. Each amp is in great shape, and I intend to only sell one. That means if one sells, the other stays. The Threshold is 50 watts of class A sound and I have always loved it. I did change the binding posts on the rear to high priced copper ones. I also replaced every fuse with those pricey fuses(five fuses in all). On the bottom I have added Dynamat under the transformer to absorb any vibration. The other amp has only one mod, and that is the addition of a IEC power outlet on the back. My opinion of the Forte' is a more open sound and a lot more power-200w/ch! The Threshold should sell for $450, and the Forte' will price at $500. Both to be paid by buyer in either case. Thx for reading this....Greg
